IMPROVEMENT IN LEATHER- PUNCHING MACHINES.

Specification forming part of Letters Patent No. 177,159, dated May 9, 1876; application filed March 25, 1876. I I

the following is a specification:

Our invention consists of a contrivance or devices for punchin g leather straps of all kinds, but more particularly bars for leather fly-nets for horses, the same beingadapted for punching either by movable or stationary punches, and

,a feed mechanism worked by a shaft fixed transversely under the bed, to be turned byv hand or other means.

Figure 1 is a longitudinal sectional elevation ofour improved machine. Fig. 2 is a plan of the machine inverted. Fig. 3 is an end elevation, and Fig. 4 is a detail of the contrivance for working the movable-punch.

Similar letters of reference indicate corresponding parts.

A is the bed of the machine, under which is a cam-shaft, B, carrying cams O, D, and E, and the crank F.

The cam O pushes the leather to be punched up against the punches G by the movable punching-bed H, which is pivoted to and has a rocking seat, I, on the bar J, which rests on the cam, and ispivoted to the frame at K, to keep it in position, and allow the bed H to rise and fall with the cam.

' The punches may be stationary or movable. In Fig. 1 they are represented stationary, being attached to a stock, L, which is fastened in a cross head, M, supported on the standards N, the stock being adjustable up and down on the standards to regulate the height of the punches, and the punch-stockis jointed at O, to allow the punches to be self-adjusting to the face of the bed H. The punches will, in practice, be adjustable toward and from each other when two are used, to be set according, to the distance apart the holes are required to be.

- For some work it is desirable to use movable punches, which we provide for by employing the "ertical sliding bar. P, with top overhanging the bed, to carry the punch-stock L,

said bar being fitted in the ways Q in one side' of the frame, and worked by the cam E, the cross-head M and posts N being removed.

The spring-presser S is employed to strip the straps off the. punches.

T and U represent the guides for regulating I claim as new and desire to secure by Letters Patent- 7 1 1. The combination of bed H, earn 0, and punches Gr, substantially as specified.

2. The feeder W, slide X, cam D, crank F, and presser Y, combined with puuchesG, substantially as specified.

3. The presser Y, forked elbow Z, and spring Z, combined with the feeder W, substantially as specified.

'4. The vertically -sliding punch carrying bar P, arranged in ways in the side. of the frame, and overhanging the bed, and the cam E, combined and arranged substantially as specified.

5. The jointed punch-stock L, in combination with the bed H, substantially as specified.
